🔀 Learn Git & GitHub — Version Control & Collaboration Masterclass
Git is the world’s most popular distributed version control system, and GitHub is the premier cloud platform for code hosting, collaboration, open-source development, and CI/CD automation. Mastering Git and GitHub is an essential core skill for every software engineer, web developer, and DevOps practitioner.
🟢 Beginner to Advanced: Start with basic repository initialization and commit lifecycles, master branching, merging, conflict resolution, rebasing, and stashing, and proceed to GitHub remotes, pull requests, SSH authentication, GitHub Actions CI/CD, and professional open-source workflows.
📖 What You Will Learn
- Distributed version control fundamentals vs centralized systems
- Git installation, environment setup, and global configuration (
git config) - Repository creation (
git init), file states, working directory, staging area (index), and commit history - Inspecting changes (
git status,git diff,git log --oneline --graph) - Ignoring files cleanly using
.gitignorepatterns - Undoing changes safely (
git restore,git reset --soft/mixed/hard,git revert) - Branching strategies (
git branch,git switch,git checkout) - Merging techniques (Fast-forward vs 3-Way Merge) and resolving merge conflicts step-by-step
- Advanced Git mechanics:
git rebase,git stash,git cherry-pick, andgit tag - Remote repository management (
git remote,git push,git pull,git fetch) - GitHub collaboration: Forking, Branch Protection, Pull Requests (PRs), and Code Reviews
- SSH key authentication setup and security best practices
- GitHub Features: Issues, Project Boards, GitHub Pages hosting, and GitHub Actions CI/CD
- Terminal productivity: Git aliases, custom log formats, and team Git workflows (GitFlow, Trunk-Based)

🧪 Practice Routine
- Read the explanation and understand the terminal concept.
- Open your terminal (Git Bash, Zsh, PowerShell, or macOS Terminal).
- Type out commands manually in a practice folder — never copy-paste!
- Inspect repository status using
git statusandgit log --oneline --graph. - Solve the “Try It Yourself” and “Mini Challenge” tasks in each lesson.
